摘要
为解决传统电子设计自动化(EDA)工具在审查插件时自由度低、误报率高及跨平台兼容性不足等问题,设计了一款基于公开数据库(ODB++)的印制电路板(PCB)自动化审查工具。该工具通过解耦审查流程,以ODB++文件为统一输入,兼容Altium、Cadence等多平台设计数据,最终消除格式壁垒;该工具采用模块化架构,支持动态加载安全间距(3倍线宽规则)、层间串扰(投影夹角与耦合长度判决)等核心算法。测试结果表明,该工具误报率低于3%、审查效率提升50%、输出报告支持PDF/Excel格式、可快速定位设计缺陷。该工具设计方案为高密度PCB提供了轻量化、可扩展的标准化验证方法,可显著降低人工复核成本,具有工程实用价值。
To address the limitations of traditional electronic design automation(EDA)tools,such as low flexibility,high false positive rates,and poor cross-platform compatibility.this paper presents an open data base(ODB++)-based automated PCB review tool.By decoupling EDA tools from the review process and adopting ODB++files as a unified input,the tool overcomes format barriers and supports multi-platform design data(e.g.,Altium,Cadence).Featuring a modular architecture,it dynamically integrates core algorithms like safe spacing(triple-line-width rule)and inter-layer crosstalk detection(projection angle and coupling length analysis)for precise design validation.Testing demonstrates a false positive rate below 3%,a 50%improvement in review efficiency,and PDF/Excel report outputs for rapid defect localization.This solution provides a lightweight,extensible standardized verification method for high-density PCB design,significantly reducing manual review costs with proven engineering value.
